2 Claims. (Cl. 280-792) the cans are moved manually by an operator whosimply slides the cans along the floor in groups of five or six cans.The trend toward cans of larger and larger diameters results insubstantial increases in the weight of the cans, particularly whenfilled with sliver. Thus with heavier cans to handle, it is becomingmore and more difiicult for an operator to move the cans about,especially where a particular operation requires him to slide a group ofseveral cans along the floor. In some instances it is necessary for theoperator to reduce the number of cans moved simultaneously in a groupand by so doing partially to defeat the purpose of using larger cans.

A principal object of this invention is the provision of an improvedsliver can having casters afiixed to the bottom part thereof, thecasters being arranged so as not to add materially to the height of thecan and so as to constitute a sturdy support therefor.

Another object of this invention is to provide an improved dolly whichis adapted to be aflixed to the bottom of conventional sliver cans as aunit and which facilitates the movement of the cans from place to place.

The invention in one form comprises a conventional sliver can andassociated dolly in the form of a triangular frame of unitaryconstruction which is especially adapted to receive a swivel type casterat each vertex and which is provided with symmetrical thrusttransmitting means engageable with the bottom flange of a conventionalcoiler can for securely affixing the dolly to the bottom of the can.

The invention will be better understood from the following detaileddescription taken in conjunction with the accompanying drawings in whichFig. 1 is a side view of a coiler having a wheel mounted can; Fig. 2 isa view of the bottom of a coiler can to which a dolly constructedaccording to this invention is afiixed; Fig. 3 is an enlargedperspective view of a caster used in the invention; and in which Fig. 4is a sectional view of a portion of the dolly showing the cooperationbetween the dolly and the coiler can.

With reference to Fig. l the numeral 1 designates a coiler base on whicha pedestal 2 is securely affixed in conventional fashion. Mounted atopthe pedestal 2 is a coiler head generally designated by the numeral 3.As is well understood in the art. suitable mechanism is provided and isdisposed within the pedestal 2 for imparting rotary motion to a platform4 rotatably mounted on the base 1. Suitable motion is imparted to asliver fed into the top of the head 3 whereby the sliver is coiled in apredetermined pattern within the can 5 mounted on the rotatable platform4.

As can be seen in Fig. 1 the can 5 is provided with a plurality ofrollers 6.

2,920,902 Patented Jan. 12, 1950 As' is disclosed in detail inco-pending application Serial Number 744,510 filed June 25, 1958, therotatable platform 4 is constructed so as to enable an operator readilyto position the can 5 in its proper centered relation to the'rotatableplatform 4 and so as to engage the rollers 6 and thereby to hold can 5in position on platform 4. I 1 i p From Figs. 2 and 4 it can be seenthat the casters 6 are affixedto a triangular frame 7 of unitaryconstruction and that an integral caster mounting base 8 is provided ateach vertex of frame 7. Each mounting base 8 is of armate configurationas indicated at 8A so-as to allow the mounting bases to fit in closeproximity to the can flange. The mounting plate 9 of each caster isaflixed by bolts '10 to the" associated mounting base 8.

As is best shown in Fig. 3 each caster 6 is of conventional design andcomprises a wheel 11 mounted on an axle 12 supported by a U-shaped yoke13 the bight portion 14 of which is secured to a swivel pin 15. Mountingplate 9 is provided With a central aperture through which pin 15 isextended. Also mounted between plate 9 and yoke 13 is a lower bearingrace 16 and an upper bearing race 17 between which ball bearings 18 arecaptured. Bearing races 16 and 17 are both provided with a centralopening for receiving the pin 15 which pin serves to hold the bearingraces and bearings together.

For the purpose of securing the frame 7 in position on the can 5 aplurality of set screws 19 are threaded through tabs 20 formedintegrally on each mounting base 8. These set screws are simple adjustedto engage the inner surface 21 of the can flange 22.

For the purpose of establishing a balanced distribution of thrust forcesexerted by set screws 20 each set screw is disposed generally radially.In. this fashion the dolly frame 7 is secured within the flange 22 andthe balanced forces exerted on the flange apply a minimum of distortionto the can flange. Since the dolly is received within the can flange 22it does not add materially to the height of the can. Furthermore, thedolly does not pound the can bottom 23 because the Weight of the can istransmitted to the dolly through the set screws 19 and the sturdy flange22 and because the upper surfaces of the dolly are completely flat. Thecan may be conventional and the dolly constructed according to thisinvention can be easily applied to the can without modifying the canitself.

While I have shown a triangular frame with three casters, it will beunderstood that a greater number of sides for the frame could beprovided together with a corresponding number of casters.

I do not wish to be limited to the particular embodiment of theinvention shown and described and I intend in the appended claims tocover all changes and modifications as fall Within the true spirit andscope of the invention.

What I claim as new and desire to secure by Letters Patent of the UnitedStates is:

1. A sliver can dolly for removable mounting inside the bottom flange ofa coiler can, said dolly comprising a multisided frame, a mounting baseconstituting an integral junction for adjacent ends of the sides of saidframe, the sides of said frame and said mounting, bases being flat onthe top surfaces thereof, a plurality of swivel type castersrespectively aflixed to the bottom surfaces of said mounting bases, aplurality of downwardly extending tabs respectively forming an integralpart of said mounting bases, and a plurality of set screws respectivelyin threaded engagement with said tabs and extending entirelytherethrough and outwardly therefrom to exert a thrust against theinside of the can bottom flange and thereby to form a frictional supportfor the can, the axes of said set screws being spaced from theassociated caster and extending in a generally radial direction withrespect to said frame.

2. A mobile sliver can comprising a substantially flat bottom, a sturdybottom flange secured to said bottom, a plurality of rod-like elementsjoined at their'ends by a plurality of integral mounting bases to form aframe of generally polygonal form, the upper surfaces of said rod-likeelements and of said mounting bases being continuous and substantiallyflat and the peripheral outer surfaces of said mounting bases beingconfigured to conform to the inner surface of said flange, a pluralityof downwardly extending tabs respectively formed on said bases, aplurality of set screws respectively in threaded engagement with saidtabs and disposed radially of said flange so as to exert an outwardthrust against the inner surface of said flange, the axes of said setscrews being spaced from the center of their respective mounting basesand said set screws being frictionally engageable with the inner surfaceof said flange whereby to form an operative support connection betweensaid can and said dolly and a plurality of casters respectively mountedon the bottom surfaces of said mounting bases.
